VALVE.

SPECIFICATION formingpart of Letters Patent No. 227,193, dated May 4,1880.

Application filed December 8, 1.879.

To all whom it may concern Be it known that I, PETER WHITE, of St.Louis, Missouri, have made a new and useful Improvement in Valves, ofwhich the following is a full, clear, and exact description, referencebeing had to the annexed drawings, making part of this specification, inwhich- Figure l is a longitudinal section of the invention, the vvalvebeing closed; Fig. 2, a longitudinal section taken at right angles tothat of Fig. l, and showing the valve opened; and Fig. 3, a detail,being -a longitudinal section taken through the lower end of thevalve-rod, and showing the valves in section.

The same letters denote the same parts.

The chief advantages of this improvement The valve is readily opened andclosed, and in cases where the valve-chest and valve-stem are extended,as in a hydrantvalve, it is self-closing, an improved means for shuttingoft the waste in opening the valve is obtained 5 the water from the maincan iiow directly through the valve-chest without interruption whetherthe valve is opened or closed, enabling the valve to be used withoutinterfering with the delivery of the water at other points; the lift ofthe valve can be regulated; the working parts can be easily withdrawnfrom and replaced in the valve-chest; the improvement is adaptable to ahydrant, a nre-plug, a beer-cock, or an ordinary faucet; it also allowsof the discharge being in the upper stories of a building, while thelower end of the construction, including the wasteopening and the valveproper, may be in the cellar, or sufficiently low to prevent troublefrom freezing; and the means for operating the valve may be arranged atany point between the ends of the valve-chest.

It consists partly in the combination of the two lower valves and thesupply-pipe, partly in the combination of the two upper valves and thewaste-opening, partly in the combination of the three valves, and thesupply-pipe, perforated valve-stem, and waste-opening, and

partly in various details, all as hereinafter specifically set forth.

Referring to the drawings, A represents the point of supply, and Cvalve-chest, B the the discharge.

The chest is-substantially a the upper end of the 5 5 ments of the kindof valve in which the im- 6o provement is beingused. If amer-faucet, asshown, it may have a taper, a?, at the end that is driven into the keg.The chest also may be of any length according to the character of thevalve. It may, forinstance, enough to reach from the cellar to theuppermost story of a building, or it may have the proportions of anordinaryfaucet.

D represents the valve-stem. its upper end it is made in provided with arack, d.

E represents a shaft having a handle, e, and extending through astuffing-box, e', into the valve-chest, and provided with a pinion, e2,which engages with the rack d, and thereof the valve-stem can be movedlon gitudinally in the valve-chest. The lower end, d, of the stem ismade hollow, the perforation extending from the lower end of the stemupward to the point or points d2 d2', the interior a3 of thevalve-chest.

F G Hrespectively represent three cup-leather valves attached to thestem D between the two yends of the perforation cZ/ that is, the valveAt or near be long the form of or is 7o by means where it opens into 8oF is attached to the stem above the opening into the perforation d', andthe ange j' of the valve is turned upward, the valve Gr is arrangedbelow the points d2 d2, and the iiange g of the valve turns upward, andthe valveH is arranged between the valves F and G, and the iange 7L ofthe valve turns downward.

The valves F and H are spaced apart a distance equal or thereabout tothe diameter of the supply-pipe B.

I represents an extension of the supply-pipe, 9 5

leading from the valve-chest or in any desired direction.

J represents a waste-opening through which the water' is drained fromthe interior ai of the valve-chest.

K represents a plug that closes the lower end of the chest, and L a plugthat closes the upper end of the chest.

The valve-stem, when raised, may be made to encounter the plug L, and byscrewing the latter farther into the chest the lift of the valve may beshortened.

The upper end of the stem may be provided with a packing, M; and, ifpreferred, another packing, N, may be used to close the opening into thecap when the valve-stem is raised, as indicated in Fig. 2.

The operation of the invention is as follows: Let the valve be closed,as in Fig. 1. The valve F then prevents the descent of the water belowthe level of the supply and from entering the perforation d at the lowerend thereof. The valve H prevents the water from passing upward into thechamber' a3, and thus the Water can iiow onward through the pipes B IWithout interruption or waste. To open the valve the handle e isrotated, causing the pinion e2 to rapidly lift the stem and bringing theparts into the position shown in Fig. 2. The water can still iiow freelyonward into the pipe I, but it can also now pass into the perforation dat the lower end thereof, thence through the outlets at d? d2 into thechamber a3, and thence out at C. In this position the valve Gr is abovethe Waste-opening J and the valve H below it, preventing any waste ofwater while the valve is open but as soon as the valve is closed thevalve G is brought below the opening J, and the water in the ch amber a3can now drain out, preventing trouble from freezing.

The shaft E projects beyond the valve-stem and is furnished with ajournal, c3, which turns in a bearing in the valve-chest. This serves tohold the shaft properlyr and to facilitate the operation of the valve,especially in closing it, for an important aim and benefit of the rackand pinion is to enable the valve to be selfelosin g, the Weight of theparts being sufficient in a hydrant to cause the valve to descend andclose.

The perforation a serves as a guide for the valve-stem.

A further advantage of the rack and pinion is that it provides formoving the valve rapidly, and the valve can be hammered upon its outeror upper end (as is often done in using beer-cocks) without injury.

The stem, if desired, may seat upon a leathern washer, k.

I claim- 1. The combination of the chest A, having the perforation af',and the stem D, having the packing M, substantially as described.

2. The combination of the chest A, stem D, valves F and H, and pipes BI, said pipes being opposite each other, substantially as described.

3. The combination of the chest A, stem D, pipes B I, arranged as shown,and valves F, G, and H, said chest having the waste-opening J, arrangedas shown, substantially as described and shown.

4. The combination of the chest A, having the waste-opening J, arrangedas described, the pipes B and I, the stem D, having the perforation d',and the valves F G H, substantially as described.
